The 2nd embodiment

In Figure 11, the fixing pedestal of simulated humanbody device 101 on the turntable on the floor that is disposed at anechoic chamber, 401 403 makes turntable 403 rotatable by motor, and by Rotation Controllers 408 its rotations of control.In addition, constitute determined antenna 402 by simulated humanbody device 101, portable radio communication apparatus 111 and turntable 403, anechoic chamber, 401 inside, relative with determined antenna 402 to position configuration for example as the receiving antenna 405 of Yagi antenna.

When measuring, make turntable 403 rotations, from portable radio communication apparatus 11 radiation electric waves, receive the electric wave of radiation by receiving antenna 405, receive the radio signal of the electric wave that is received by radio receiver 406, and after carrying out processing such as high frequency amplification, frequency inverted and detection, the electric signal after the detection is inputed to the system controller 407 that comprises network analyser.System controller 407, mensuration begun and measure the control signal that finishes etc. and export to Rotation Controllers 408, and measure antenna performances such as the radiation graphics feature of antenna of portable radio communication apparatus 111 and input impedance characteristic according to the electric signal after the detection, and its measurement result is illustrated on the CRT monitor 409.In this case, as shown in figure 12, adjust the interval d of the portable radio communication apparatus 111 that makes the hand 106 that is contained in simulated humanbody device 101 and the trunk 103 of the simulated humanbody device 101 of PDA posture and with respect to the tilt angle theta of the portable radio communication apparatus 111 of the angle of depression direction of simulated humanbody device 101 (in Figure 12, for the anglec of rotation, hereinafter referred to as the angle of inclination from the X-axis on XZ plane) be certain value.Like this, by the radiation graphics feature or the impedance operator of antenna that the interval d of simulated humanbody device 101 and portable radio communication apparatus 111 or tilt angle theta are had as parametric measurement portable radio communication apparatus 111, and can measure the influence of human body accurately to portable radio communication apparatus.In this case, so-called radiation graphics feature, be meant for the directivity power gain characteristic of shear surface arbitrarily, but the present invention is not limited thereto, also can be: antenna performances such as the emission efficiency of calculating from directivity power gain characteristic, actual gain etc. or diversity antenna gain, the multidirectional gain characteristic that comprises phase information, related coefficient.

Figure 13 is illustrated in the shape of portable radio communication apparatus 501 used in the antenna characteristic determining system of Figure 11 and the stereographic map of size, the measurement result that Figure 14 is to use the antenna characteristic determining system of Figure 11 to measure, the antenna emission efficiency of expression portable radio communication apparatus 501 is with respect to the curve map of interval d, the measurement result that Figure 15 is to use the antenna characteristic determining system of Figure 11 to measure, the antenna of expression portable radio communication apparatus 501+antenna gain of directions X is with respect to the curve map of interval d.

In Figure 12, expression simulated humanbody device 101, with position relation and coordinate system as the portable radio communication apparatus 501 of terminal model, as shown in figure 13, as the portable radio communication apparatus 501 of terminal model, have the metal framework 502 of rectangular shape of long 12.5cm, wide 3.5cm, thick 2cm and the 1/4 wavelength unipole antenna 503 of long 8.3cm.1/4 wavelength unipole antenna 503 configured in parallel along its length and carries out feed from the feeding point 504 of the connecting portion of the upper end that is in metal framework 502 in metal framework 502 upper ends.In addition, in Figure 12, being made as d with the interval with feeding point 504 and the directions X of the trunk 503 of simulated humanbody device 101, is 50 ° mode from the angle of depression of X axis Z-direction, and the portable radio communication apparatus 501 of terminal model is installed the hand 106 that remains on simulated humanbody device 101.

In Figure 14, be illustrated in keep by the hand of simulated humanbody device 101 as the portable radio communication apparatus 501 of terminal model state, d changes under the situation of 13,16,20,25,30 (cm) at interval, utilizes the measurement result of emission efficiency of the antenna characteristic determining system measurement of Figure 11.In Figure 15, be illustrated in and measure under the frequency 900MHz+measurement result of the directional gain of directions X.

From Figure 14 and Figure 15 as can be known, the emission efficiency of the antenna of portable radio communication apparatus 501 increases with interval d, is improved, and the change of the antenna gain relative spacing d of+directions X is periodically-varied.In this case, be respectively roughly 23,39 at interval d, antenna gain maximum during 55cm, be roughly 0dBi.Be respectively roughly 14,32 at interval d on the other hand, antenna gain minimum during 48cm, be roughly-10dBi.Like this, big with respect to the variation of emission efficiency in the variation of the antenna gain of+directions X, mean that the simulated humanbody device 101 and the reflecting plate of corner reflector antenna carry out same action.Promptly, if from the electric wave of wavelength X from antenna after the radiation, by 101 reflections of simulated humanbody device, path when returning antenna adds up to λ/2, then the electric wave of Fang She electric wave and reflection back incident is because opposite so cancel out each other in the aerial position phase place, if the path adds up to λ, be same-phase then, so mutually promote.This can be represented by for example following formula.

[formula 1]

d＝λ/4+(nλ)/2 (1)

[formula 2]

d＝(nλ)/2 (2)

Here, n is the integer more than 0.Above-mentioned formula (1) is+situation of the directional gain minimum of directions X, and above-mentioned formula (2) is+situation of the directional gain maximum of directions X.In fact because the shape of human body has fluctuating, so the absolute value of d is not strict at interval, thus every approximately λ/2 periodically repeatedly power be important, it just can obviously be found out from Figure 15.For example, λ when frequency of utilization f is 900MHz/2 are 16.7cm, are the condition of mutually strengthening as can be known by following formula (20), maximum during d=20cm at interval in Figure 15.But as can be known: in the directional gain minimum of interval d=13.30cm time+directions X, the variable quantity of interval d at this moment is the 17cm suitable with λ/2.

Thus, as shown in figure 18, when a plurality of antennas 1303 of configuration on portable

radio communication apparatus

111,1305 o'clock, in the PDA posture, in order to make each

antenna

1303,1305 with the interval d1 of the trunk 103 of simulated humanbody device 101, the absolute value d0=|d1-d2| of the difference of d2 is (in Figure 18, the interval d1 of the horizontal direction when for example tilting to keep portable radio communication apparatus 111 with angle of inclination 50 degree and d2's is poor) be λ/4,3 λ/4,5 λ/4,7 λ/4 ... promptly, make d1 at interval, the absolute value d0 of the difference of d2 is a following formula, by in the position of the maximal value and the minimum value of antenna gain (if the antenna in a side position be the minimum value of antenna gain the antenna one of the opposing party position is decided to be peaked position) dispose each

antenna

1303,1305, and can improve diversity for+X-direction, in view of the above, can improve the receiving sensitivity and the radioactive nature of delivering letters of the essence of radio communications set 111 significantly.

[formula 3]

d0＝λ/4+(nλ)/2 (3)

Here, n is the integer more than 0.In addition, as shown in figure 18, though the position of the trunk 103 when measuring interval d1, d2 is in fact different, slightly different in the horizontal direction, but in the design of the aerial position of portable radio communication apparatus 111, also the different essence of this position can be set at zero, be suitable for above-mentioned formula (3).But, when the position of the vertical direction of 2 antennas of portable radio communication apparatus 111 significantly not simultaneously, as shown in figure 18, need to consider by trunk 103 (when the design of portable radio communication apparatus 111, be not limited to the trunk 103 of simulated humanbody device 101, also can consider actual user's size or standard or specific size) interval d1, the d2 of reality of the different and horizontal direction that produces in position, be suitable for formula (3).

In addition, the situation in sighting distance at portable radio apparatus and base station, for example lively area such as station or park is in the sighting distance under the situation in the communication environments, the time occupancy of expecting the antenna that the reception rank is high when diversity reception easily is very high, therefore, can directly use the communication quality that improves portable radio communication apparatus by receiving the high antenna of rank as transmitting antenna.In this case, if the absolute value of the difference of interval d1, the d2 of each antenna and human body is λ/4 then more effective.For example, under the situation of the application that 2GHz is with, because λ/4 are 3.75cm, so with 2 antennas of 3.75cm arranged spaced, directly use receiving the high antenna of rank as transmitting antenna, then with the situation of 5cm arranged spaced antenna compare the posture in the time of to alleviate by the PDA posture and the antenna sensitivity that causes descends.Also identical under the situation of the application that 5GHz is with, because λ/4 are 1.5cm, so with 1.5cm or 2 antennas of 4.5cm arranged spaced, directly use receiving the high antenna of rank as transmitting antenna, then with the 3cm of the natural several times that constitute λ/2 or the situation of 6cm arranged spaced antenna compare the posture in the time of to alleviate by the PDA posture and the antenna sensitivity that causes descends.Under the situation of the application of 8GHz band,,, also can access same effect in this case so also can utilize periodically-varied, for example with 3 λ/4 interval or 5 λ/4 arranged spaced antennas because λ/4 be below the 1cm.
